The comet Lovejoy in that day has been positioned at eastern region of Sagittarius, can be observed in lower southeast skies. It was bad transparency condition, I could not detect the coma by naked eyes through a telescope. The comet has a coma brightness of about 9th magnitude estimated from this picture, and you can see a short tail in west direction.
